Optical Audio Cables

To make your job easier, we scoured the internet and found you the best optical audio cables. These options will fulfil every need of yours, and are available at every price point. We have included only the best ones for you, so quality will not be something you need to question!

What does an optical audio cable do?

An optical audio cable is a particular kind of cable that can be used to send audio signals between various devices while retaining more signal fidelity than some other signal transfer techniques. These cables can be made in a variety of ways, but they all use optical fibres to convey a signal that can be seen as red light. Optical fibres are typically composed of quartz glass or fibre optics.

Although many high definition televisions (HDTVs) use these cables as well, optical audio cables are often used to connect devices that employ digital audio signals, such as audio transmissions between a compact disc (CD) player and a receiver.

The optical audio cable, also known as a ToshibaTM Link or TOSLINKTM cable, was initially created by ToshibaTM for audio signals between CD players and stereo receivers. Since then, it has evolved into the industry standard for digital audio signal transmission between devices. This kind of cable is known generically as “optical audio cable,” and any manufacturer’s cables can be referred to by this name. The output and input connections of various audio devices and circuits can be connected to the single terminals that these cables normally have at each end.

An optical audio cable can often be as long as 32 feet (10 metres), though shorter lengths are frequently used. Although longer cables are possible, signal loss usually happens unless a signal booster is employed along the wire. An optical audio cable can be used to connect a wide range of gadgets, including common media player gadgets like CD players and receivers for home theatre sound systems.

In order to assure better sound quality, HDTVs frequently feature connections for optical audio that enable an audio signal to be transferred from the TV to a receiver, typically for a home theatre system. It is advised to try to use HDMI cables in place of optical audio connections, as much as possible because of one singular reason. Higher-quality audio, including Blu-ray codecs like Dolby True HD and DTS HD Master Audio, can be sent via HDMI cables. However, this feature cannot be performed by optical audio cables.

Use an optical audio cable only in the case that you have older equipment that does not support HDMI. To know more about this, you can watch the video below.

Factors to look for

Now that you know what the purpose of an optical audio cable is, you are probably looking for the best one in the market right now. Well, before we give you the 9 optical audio cable to choose from in 2023, it is important to know what characteristics are the most important while shopping for an optical audio cable. A good mixture of all these characteristics will make for the best optical audio cable you can buy.


Due to their greater bandwidth needs, optical audio cables will usually cost more than digital coaxial cables. They don’t interact with other surrounding electrical devices, but as a trade-off, they perform better when replicating digital signals.

As a result, the type of optical cable you decide to buy will have a big impact on the price you charge. Quartz fibre cables are substantially more expensive than plastic fibre cables of the same standard length of 5 metres. Additionally, some cables have connectors that are 24k gold-plated to enhance signal transmission and lessen corrosion. The cost of the cable, however, can potentially increase quite a bit as a result of this.

Make sure that you are only buying the cable that fulfils your requirements without added factors that will not be of help to you.


It is advised that the length of your optical audio cable remains under 10 metres since it reduces the reliability of the transmission. Usually, optical audio cables frequently have a maximum length of 5 metres and require an additional signal booster if they are longer than that. A signal booster would cost extra money as well, so it is recommended to buy an optical audio cables under 10 metres unless you absolutely require it.

For instance, let’s say you need lengths of more than 100 feet. An optical cable composed of molten quartz would be your ideal choice in that situation because it will produce outcomes of a higher calibre. Alternatvely, let’s say you only require a short wire as an example. In that situation, an optical fibre cable composed of plastic may be used.

It is clear from the above examples that length of the wire has an impact on what materials the wire is made up of, and subsequently, the price of the wire.


The performance of the 5 mm and 8 mm cables is identical. This is due to the fact that the connections are unaffected by the width, which is simply the cable’s outer diameter. There is therefore no distinction between the two sizes. But you should be aware that thicker cables endure longer and frequently include a protective nylon mesh covering on the outside. That is something that you might want to think about.

The difference in quality between several types of optical audio cable is not particularly noticeable. For instance, let’s say you have a very advanced system but average hearing. If so, it is unlikely that using a less expensive brand in place of a more expensive one will result in any changes being heard. Even if you have a very good system, this is the fact.


For the best performance, your optical audio connection must have a bandwidth that falls between 9 MHz and 11 MHz. This connection will perform more efficiently the more bandwidth it has. It is crucial to remember, though, that smaller consumer goods, like CD players, would not suffer a quality loss as a result of constrained bandwidth in the same way that a home theatre system would.
